Rograkh, Son of Rohgahh / Thrasios, Triton Hero

How it plays & wins

This is a Thrasios and Rograkh partner deck built around fast mana, cheap free interaction, and creature tutoring. Moxen, Sol Ring, Mana Vault, Lotus Petal, and mana dorks like Birds of Paradise and Delighted Halfling power out early plays. Force of Will, Fierce Guardianship, Pact of Negation, Swan Song, and Flusterstorm protect the turn, and Rhystic Study and Mystic Remora provide card advantage. Green Sun's Zenith, Chord of Calling, Eldritch Evolution, and Finale of Devastation find the right creature for the situation.

The win condition isn't clear from the list, and I don't see a defined infinite combo. The most plausible route is a go-wide mana turn: Chatterstorm makes tokens, Cryptolith Rite and Gaea's Cradle turn them into mana, and Underworld Breach adds extra spell turns. Otherwise it likely grinds with value and a creature beatdown while holding up counters.
